Benefits for Metal Cutting Manufacturers

The APEC MT Series gantry bridge mills help manufacturers produce large, complex parts with greater accuracy, stability, and reliability, ensuring their customers receive high-quality end products that meet the strictest aerospace standards.

  • Rigidity for heavy cutting – the U-shape gantry structure directs cutting forces into the base, reducing vibration and improving tool life.
  • High accuracy and repeatability – precision ball screw drives and Heidenhain/Siemens control deliver ultra-tight tolerances and consistent surface finishes.
  • Cycle time reduction – high acceleration/deceleration with powerful spindle torque allows faster roughing and efficient finishing in a single setup.
  • Ultra-fine surface finishes – advanced spindle options and high-speed contouring enable mold-quality finishes directly on aerospace structures.
  • Reliability and uptime – reinforced castings, thermal stability, and intelligent cooling/chip evacuation systems ensure 24/7 dependable performance.

By combining rigid gantry bridge design with advanced control, spindle, and tool management technologies, the MT Series provides manufacturers with a cost-effective, long-term solution for large aerospace machining programs.

Key Features

  • U-shape gantry bridge mill design – provides unmatched rigidity and stability during high-force cutting of titanium and nickel alloys.
  • High-speed and high-torque spindles – options up to 20,000 rpm with heavy torque ratings for both roughing and finishing operations.
  • Linear guideways and dual ball screws – ensure smooth, backlash-free movement for precise contouring of complex aerospace geometries.
  • Head exchange capability – supports multiple spindle head configurations for different cutting strategies and materials.
  • Crossbeam flushing and chip evacuation – high-pressure nozzles clear chips quickly, improving reliability and reducing downtime.
  • Advanced coolant and lubrication systems – including spindle chillers and oil-air lubrication for consistent thermal stability.
  • Fully enclosed work area – guarantees safe operation, efficient coolant containment, and cleaner shop environments.
  • Industry-standard CNC controls – Heidenhain iTNC or Siemens options for 5-axis simultaneous machining and proven aerospace programming cycles.

Ideal Cutting Applications

The APEC MT Series is purpose-built for aerospace structural machining and other industries requiring heavy-duty 5-axis contouring:

  • Wings and fuselage panels – precision machining of large aluminum and titanium surfaces.
  • Spars and ribs – thin-wall aerospace structures requiring rigidity and accuracy.
  • Bulkheads and frames – complex monolithic aerospace components.
  • Engine components – titanium and Inconel cases, mounts, and structural housings.
  • Landing gear parts – high-strength alloy machining with deep material removal.
  • Defense and energy – structural frames, housings, and turbine components for military and power-generation applications.
